[PATCH v2 0/3] btrfs: fix several sparse warnings

[Omar Sandoval <osandov@osandov.com>]

This patch series fixes some warnings reported by sparse when building the
btrfs module. It fixes two classes of warnings: address space warnings and lock
context warnings. This didn't uncover any logical errors, but it reduces the
noise when checking the source. There are a few less straightforward sparse
warnings still remaining.

Version 2 replaces an open-coded implementation of kernel_write in write_buf,
doesn't touch unrelated style issues, and add's David's Reviewed-by.

This patch series applies to 3.17-rc7.
